I was able to get the hosted engine started manually via Virsh after re-creating a missing symlink in /var/run/vdsm/storage -- I later shut it down and am still having the same problem with ha broker starting. It appears that the problem *might* be with a corrupt ha metadata file, although gluster is not stating there is split brain on the engine volume
I'm seeing this: ls -al /rhev/data-center/mnt/glusterSD/orchard0\:_engine/d70b171e-7488-4d52-8cad-bbc581dbf16e/ha_agent/ ls: cannot access /rhev/data-center/mnt/glusterSD/orchard0:_engine/d70b171e-7488-4d52-8cad-bbc581dbf16e/ha_agent/hosted-engine.metadata: Input/output error total 0 drwxr-xr-x. 2 vdsm kvm 67 Dec 13 00:30 . drwxr-xr-x. 6 vdsm kvm 64 Aug 6 2018 .. lrwxrwxrwx. 1 vdsm kvm 132 Dec 13 00:30 hosted-engine.lockspace -> /var/run/vdsm/storage/d70b171e-7488-4d52-8cad-bbc581dbf16e/03a8ee8e-91f5-4e06-904b-9ed92a9706eb/db2699ce-6349-4020-b52d-8ab11d01e26d l?????????? ? ? ? ? ? hosted-engine.metadata Clearly showing some sort of issue with hosted-engine.metadata on the client mount. on each node in /gluster_bricks I see this: # ls -al /gluster_bricks/engine/engine/d70b171e-7488-4d52-8cad-bbc581dbf16e/ha_agent/ total 0 drwxr-xr-x. 2 vdsm kvm 67 Dec 13 00:31 . drwxr-xr-x. 6 vdsm kvm 64 Aug 6 2018 .. lrwxrwxrwx. 2 vdsm kvm 132 Dec 13 00:31 hosted-engine.lockspace -> /var/run/vdsm/storage/d70b171e-7488-4d52-8cad-bbc581dbf16e/03a8ee8e-91f5-4e06-904b-9ed92a9706eb/db2699ce-6349-4020-b52d-8ab11d01e26d lrwxrwxrwx. 2 vdsm kvm 132 Dec 12 16:30 hosted-engine.metadata -> /var/run/vdsm/storage/d70b171e-7488-4d52-8cad-bbc581dbf16e/66bf05fa-bf50-45ec-98d8-d00002040317/a2250415-5ff0-42ab-8071-cd9d67c3048c ls -al /var/run/vdsm/storage/d70b171e-7488-4d52-8cad-bbc581dbf16e/66bf05fa-bf50-45ec-98d8-d00002040317/a2250415-5ff0-42ab-8071-cd9d67c3048c -rw-rw----. 1 vdsm kvm 1073741824 Dec 12 16:48 /var/run/vdsm/storage/d70b171e-7488-4d52-8cad-bbc581dbf16e/66bf05fa-bf50-45ec-98d8-d00002040317/a2250415-5ff0-42ab-8071-cd9d67c3048c I'm not sure how to proceed at this point. Do I have data corruption, a gluster split-brain issue or something else? Maybe I just need to re-generate metadata for the hosted engine?
